CPC classification number: G01S19/37

Abstract: Techniques are provided for employing an embedded software defined radio (SDR) in a navigation system. A navigation system implementing the techniques according to an embodiment includes a global positioning system (GPS) receiver configured to acquire and track received GPS signals. The system also includes an SDR configured to process received communication signals. The communication signals include timing data. The SDR is further configured to calculate position and navigation data based on a combination of the processed communication signals and the tracked GPS signals provided by the GPS receiver. The system further includes a system timer configured to provide a common time base for use by the GPS receiver and the SDR. The navigation system is implemented in an application specific integrated circuit (ASIC).
